BH board - dwell setting stays a "5" no matter what

the dwell setting on my BH board stays at 5 ms (five flashes solid yellow) no matter what. I tried a board reset and a fresh battery - to no avail. This board hasnt seen 10 cases yet so I am a little frustrated to say the least. Any ideas?

OK, I fixed the board issue with the help of Phil from GoG. However the issue (gun only making a "puffing" sound when I try to fire paintballs but dry firing works just fine) appears to be caused by something other than the dwell setting. I am a bit at a loss here because it was working fine, sat in my gearbag for a couple weeks and then starting acting up. Air system causes no issues with my other guns & i used a fresh quality battery. Any ideas? O-ring were swapped recently (gun shot fine afterwards for about a case).
